Hi, we would be grateful for some advice.
On a recent trip in the cali, we noticed condensation spreading across the tailgate window. Having wiped it down inside and out, we realised the condensation was inside the window, i.e. between the panes of glass. It looks like the seal inside the window itself is malformed in both of the top corners, as shown in the pictures.
Note: we have the thermal tinted double-glazed window, that does not have the defrosting wires.
We contacted our local VW garage on our return and arranged to take it in for investigation. The diagnostic test detected the following issue with the seal between the glazing and the chassis of the vehicle: "Water leak - used ultra sonic tester and found rear window will require to be removed and resealed".
We have questioned whether removing and resealing the window will resolve the problem, given the issue is with moisture in the window itself, however they have responded that they would like to do this as the first line of repair. They noted that in terms of proving a fault with the glass itself, this first repair would have to be done prior to any glass replacement under parts warranty, as VW would require them to rule out the outer sealing being the root cause of the issue. Once this has been completed, they have advised that if the problem was to recur, they would then be able to prove that the issue isn't with the sealing of the window, but with the part itself.
This is less than ideal, as we will be heading off on a 10-week trip around Europe just after Easter. We're concerned about the condensation appearing again while we're away, as it significantly impacts visibility out the back when driving.
What makes this even more frustrating is that this window was replaced by the same garage around 14 months ago, as a result of an accident while it was being serviced by them that cause the window to be smashed.
Does anyone have any thoughts or suggestions? Are we being unrealistic in expecting the garage to replace the window straight away? We sent them the photos and explained the condensation was inside the glass, but I guess we can't prove this, and the window has cleared for now.
